The continuum limit of the static - light meson spectrum
نویسنده
چکیده
We investigate the continuum limit of the low lying static-light meson spectrum using Wilson twisted mass lattice QCD with Nf = 2 dynamical quark flavours. We consider three values of the lattice spacing a ≈ 0.051 fm , 0.064 fm , 0.080 fm and various values of the pion mass in the range 280MeV ∼mPS ∼ 640MeV. We present results in the continuum limit for light cloud angular momentum j = 1/2 , 3/2 , 5/2 and for parity P = + , −. We extrapolate our results to physical quark masses, make predictions regarding the spectrum of B and Bs mesons and compare with available experimental results.

Light hadrons with improved staggered quarks : approaching the continuum limit
We have extended our program of QCD simulations with an improved Kogut-Susskind quark action to a smaller lattice spacing, approximately 0.09 fm. Also, the simulations with a ≈ 0.12 fm have been extended to smaller quark masses. In this paper we describe the new simulations and computations of the static quark potential and light hadron spectrum. These results give information about the remaini...
متن کاملCP-PACS results for quenched QCD spectrum with the Wilson action
We present progress report of a CP-PACS calculation of quenched QCD spectrum with the Wilson quark action. Light hadron masses and meson decay constants are obtained at β =5.9, 6.1, and 6.25 on lattices with a physical extent of 3 fm, and for the range of quark mass corresponding to mπ/mρ ≈ 0.75 − 0.4. Nucleon mass at each β appears to be a convex function of quark mass, and consequently the va...

متن کاملPrecision Lattice Computations in the Heavy Quark Sector
The phenomenology of the pseudo scalar mesons Ds and Bs and of the vector mesons Ds and B ∗ s , each of which contain a heavy and a light quark, was investigated in simulations of quenched lattice QCD. The work is particularly focused on the minimisation of all systematic errors within this approximation. The decay constants FDs and FD∗s and the difference in the masses between the pseudo scala...

We compute masses of D meson, Ds meson and charmonium states using Nf = 2 + 1 + 1 Wilson twisted mass lattice QCD. All results are extrapolated to physical light quark masses, physical strange and charm quark masses and to the continuum. Our analysis includes states with spin J = 0, 1, 2, parity P = −,+ and in case of charmonium also charge conjugation C = −,+. Computations are based on a large...
